NESAC (North Eastern Space Applications Centre)

Cherrapunji, in Meghalaya, once had just one weather radar for a region that gets the world’s heaviest rain. A short drive away in Umiam, a small ISRO centre has spent 26 years quietly changing that story — one satellite image at a time.

Must Know

The North Eastern Space Applications Centre (NESAC) is a joint initiative of the Department of Space (DOS) and the North Eastern Council (NEC).
It is headquartered at Umiam, Meghalaya, near Shillong.
NESAC was established on 5 September 2000. It is registered as a society under the Meghalaya Societies Registration Act, 1983.
NESAC applies remote sensing and satellite communication to support all eight states of India’s Northeastern Region.
Its current Director is Dr. S.P. Aggarwal, in office since 17 September 2021. He was previously Group Head of the Water Resources Department at the Indian Institute of Remote Sensing (IIRS), ISRO, Dehradun.
NESAC’s core objectives cover natural resource mapping, satellite communication for education and health care, disaster management support, and capacity building in geospatial technology.

Good to Know

NESAC’s projects span agriculture, forestry, water resources, geosciences, urban planning, geoinformatics, satellite communication, UAV applications, and disaster management.
As of July 2026, NESAC was implementing nearly 130 space application projects across the Northeast. About 50 were recently completed, and 78 were ongoing.
NESAC’s Geo-Informatics Laboratory has executed projects covering more than 2,000 square kilometres. This work spans forest carbon assessment, biodiversity conservation, mining restoration, and disaster resilience.
The Centre carries out geospatial mapping of the India-Myanmar border, along with inter-state boundaries within the Northeast.
NESAC runs a bamboo mapping programme with the North East Cane and Bamboo Development Council (NECBDC). This supports the region’s bamboo value chain and helps create rural livelihoods.
The Centre also maintains a flood early warning system and a GeoTourism dashboard called ‘ManzilNE’, promoting the Northeast’s natural and cultural heritage.

Great to Know

NESAC’s drone-based mapping has supported the SVAMITVA Scheme across more than 700 villages in the Northeast. It has also supported organic agriculture projects under PM-DevINE, benefiting nearly 25,000 farmers.
NESAC sits alongside India’s three major ISRO launch and satellite centres, but with a different role. It is a specialised regional application centre, built to serve one geographically distinct region rather than the whole country.
Pairing border-security mapping with everyday development work, in the same institution, is no accident. It reflects how space technology in India’s Northeast serves both strategic and civilian goals at once.
NESAC has trained more than 4,500 students and over 900 drone, GIS, and remote-sensing professionals through its various capacity-building programmes.

Current Affairs

14 July 2026: Union Minister Dr. Jitendra Singh visited NESAC at Umiam, Meghalaya, and reviewed its space-based initiatives. He said NESAC’s work in geospatial mapping of the India-Myanmar border and inter-state boundaries supports national strategic priorities, alongside its developmental role. (Source: PIB)
At the same review, Director Dr. S.P. Aggarwal presented NESAC’s portfolio of nearly 130 projects, including about 50 recently completed and 78 ongoing initiatives. (Source: PIB)
The Minister called for closer coordination between NESAC and the North East Cane and Bamboo Development Council on its bamboo mapping programme. He also asked NESAC to improve the precision of its flood early warning system. (Source: PIB)
The same day, Dr. Jitendra Singh also reviewed NECTAR (North East Centre for Technology Application and Reach). This is a separate Department of Science and Technology institution in Shillong, reviewed as part of a wider tour of Northeast science and technology institutions. (Source: PIB)
